Finding King Fern Valley


I had heard of King Fern Valley in the Norfolk Island National Park.  It is where you can find the rare King Fern (Marattia salicina).  I have wanted to go there for years, ever since first hearing local icons, Owen and Beryl Evans and Jackie Ralph Quintal, describe a King Fern’s grandeur.  But like Shangri-La or something from The Lord of the Rings, finding King Fern Valley has proven elusive.  Wherever I was, the Valley always loomed just over the next ridge or horizon.  So when Lyn Bryant recommended we go there one day, I quickly suggested the next available weekend.

Lyn is one of those people who wear multiple hats, but one at a time.  We knew each other well enough to say “hi” at the supermarket, but I didn’t know of her long-time interest in Norfolk history and natural history; of her collection of historical photographs or of her knowledge of the Island’s hydrology.  Wow.  One day recently, as part of their annual company party, I took the team at KC Industries and their partners on a tour of Norfolk.  By the way, it’s a particular challenge for a tour guide to show locals their own island.  It was fun and I learned a lot.  And the next thing I knew, I’m making plans to meet Lyn and Mark for a walk through King Fern Valley.

Okay, so we didn’t find King Fern Valley.  I said it was elusive.  But it was genuinely interesting to try.  Credit the Park Service with rehabilitating the forest along the Mt. Bates Track to its present healthy condition.  The re-growth is now sufficient to obscure old paths and landmarks from just a few years ago.  But in searching for a trail from the grassy forest road, Mark noticed limestone rocks underfoot.  At first thought, this was an unusual find on top of a volcanic peak.  But we quickly surmised the rock was probably calcarenite excavated from the Kingston area during World War II.  Mt. Bates was the site of a radar installation erected in 1942.  We knew the road we were on was built at that time, but evidently it was originally covered with limestone fill. 

Lyn started to become a bit embarrassed about not finding the trail, but she shouldn’t have.  I called my good friend, Ed Hooker, for some advice.  Ed has hiked across the Island countless times with the late Harry Buffett, including to King Fern Valley.  But Ed didn’t quite remember the start of the trail, either.  He thought it began down from us, near the Hollow Pine.  So we got in our cars and made our way to what remains of a huge Norfolk Island pine.

The Hollow Pine is a landmark for its sheer size and the fact that adults could comfortably stand inside its hollow trunk.  Even in death with its top portion missing, it is impressive and reminds us of how Norfolk must have been before the axe and the cross-cut saw.  I hear there are a few of these virgin-growth trees still living, but their locations are kept hidden out of concern that onlookers might adversely impact them by compacting the surrounding soil.  For that reason, a viewing platform had been constructed uphill from the Hollow Pine, but this great tree is now posing a threat to public safety and the platform has been dismantled and the trail blocked-off.  However, we were there on a mission and away from the tree began to search for a tell-tale sign of a trail leading to what I hoped was King Fern Valley. 

Okay, so Ed was mistaken.  We couldn’t find a trail.  But it was another chance to appreciate the work Parks is doing to rehabilitate the forest.  Because of the prevalence of grazing cattle before the National Park was established, much of the Park was initially filled with noxious trees and other introduced flora.  These plants are considered “colonising” species.  They are hearty and opportunistic, and hard work to cull and keep out, which is what the Parks crew has progressively been doing.  Indeed, the historical record going back to Captain Cook’s visit in 1774 speaks of Norfolk being so densely forested that there was little ground cover.  That’s what we’re seeing now: little ground cover.  The native trees need to bushy-up a little more, but it looks good and the ground is clear enough to reveal a trail – if one existed.

It’s me, of course.  Maybe I’m not supposed to know.  But we’re going to try it again on another day, and Ed will join.  King Fern Valley.  Everyone seems to have been there.  They say it’s just over the ridge.
